This thread got buried deep when I originally posted it so I've rewritten it in the hopes of actually getting some replies this time in case there's others in a similar situation or that have the same questions as me.
--
I am an absolute noob. I have done a good amount of searching, read a good amount of guides, and watched a good amount of videos about the process, but I still feel it's necessary to post here because I still need some guidance to be able to get started.
I have a Toshiba Satellite S75-A7221, which comes preloaded with Windows 8 which I have since updated to Windows 10. I would like to dual-boot Windows 10 and OS X El Capitan on the same hard drive (I have plans to eventually buy separate computers for separate operating systems; this is what I'd like to do for now) but I have a few questions about how to begin.
My specs are available
here as well as below.
Model: Toshiba Satellite S75-A7221
CPU: Intel Core i7 (4th Gen) 4700MQ / 2.4 GHz (Haswell)
Chipset: Mobile Intel HM86 Express
Graphics: Intel HD Graphics 4600, 1600x900 display
WiFi: Realtek RTL8188EE Wireless LAN 802.11n PCI-E NIC
Storage: 1TB
RAM: 16GB
UEFI.
I have a few questions I can't find the answer to myself.
- Is this a compatible build, and if it is, is there anything else I must do before or after installing OS X for it to work properly?
- I have seen a fair bit about "DSDT" "Patch your own." "You will need to patch your kernel." As much as you can throw guides at me, I can't say I can make too much sense of them. I get that there's some level of Terminal and BIOS preparation but I don't understand the significance of these, or the pros/cons of using DSDT or other additional tools. Where do I go, how do I start, and furthermore, what is it? The page containing the definition of DSDT is broken.
- This is an important one and I am surprised not to have seen it before. I don't know how to get the Windows ISO or how to prepare the USB for Windows -- or if I even need one. I saw a little something about a program called Rufus and a thread or two about reducing the size of the current Windows install and partitioning the drive a certain way so that when OS X is installed on the same drive it will recognize it and respect it. The Rufus method as I mentioned earlier appears to require a Windows ISO, online what appears to be used is the developer pre-release version of Windows 10. I don't know if this is necessary or not seeing as I'm already running Windows 10 Home.
- I don't know how many USBs to buy, or of what sizes. Some guides say one, some say 2, some 3, some even 4, and mixes of 8GB & 16GB. As I stated at the beginning of this thread this is a temporary solution to boot two operating systems. I understand it is best to use two SSDs for each OS but for now this is all I can do.
I am left wondering just where to begin so I don't end up with a laptop without any functional OS at all.
I am sorry to come off as so slow. I am in a kind of rough situation here and I would love some pointers. Thank you in advance to anyone who can offer help.
again, edit -- i'd like to clarify that i haven't done anything to the bios or anything hackintosh related to this computer so far. i have simply updated it to windows 10 since i have bought it. this thread is for getting help about beginning the process and also to get answers to the questions above.
